Emission and Spectra


This section is just for some raw values, useable for different purposes.

Electromagnetic Spectrum

Type WaveLength
Cosmic radiation > 10-5 nm
Gamma radiation < 0.01 nm
Hard X-rays < 0.1 nm
Soft X-rays < 10 nm
Vacuum ultraviolet < 200 nm
Far ultraviolet < 300 nm
Near ultraviolet < 390 nm
Violet < 455 nm
Blue < 492 nm
Green < 577 nm
Yellow < 597 nm
Orange < 622 nm
Red < 770 nm
Near infrared < 1.5 µm
Middle infrared < 6 µm
Far infrared < 1 mm
Microwaves < 1 m
Radiowaves < 10 km
Long Oscillations > 10 km

Overall definitions and wavelengths are topics of discussion. Cosmic radiation could be interpreted as a complex mix of frequenzies ("white" noice), and "soft"- gamma radiation and hard X-rays can be interpreded as overlaping (However, the source of radiation is different by nature).
